To all whom 'it may concern.'

Be it known that we, ARTHUR J. Honor; and HENRYV B. RUGGLEs, citizens of the United States of America, residing at Pasadena, iin the county of Los Angeles and State of California, have invented certain newY and useful Improvements in Pulp Gathering, Transferring, Squeezing, andv Forming Devices, ofwhich the following is a specication.

This invention has relation to certain new and useful improvements in pulp gathering, transferring, squeezing and forming devices and has for its primary object to provide a device of this character/in which the gathering' and transferring plate will be adapted to reciprocate toward and Vaway from the upwardly and spirally moving forms traveling through the pulp containing tank to gather pulp from the tank and transfer same to said forms and press the pulp and squeeze the saine against the outer faces of said forms as the gathering and transferring plates move in a horizonta plane around' the moving forms.

The invention has for another object, the provisionof a series of circularly arranged arcuate pulp gathering and transferring plates within the pulp containing tank and around the stationary shaft extended through said tank, to gather pulp and transfer the same to connected forms or former-sections movable spirally upon said shaft and through the tank, the arcuate pulp gathering and transferring plates also serving to squeeze the pulp and force liquid from the same and compress said pulp upon said forms or former-sections.

Another object ofv the present invention resides in the provision and arrangement of transversely curved and separated pulp gathering and transferring plates carried by a traveling ring gear encircling the stationary shaft and the moving forms upon the same, and mechanism whereby alternate pulp gathering and transferring plates of the series may be forced inwardly toward the moving forms to transfer pulp to the latter and compress and squeeze said pulp upon said forms while the remaining pulp gathering and transferring plates of the series are moving outwardly away from said moving forms to gather a fresh supply of pulp to be squeezed and pressed against the moving forms upon the return or inward movement of t-he last mentioned pul-p gathering and transferring plates as the first mentioned pulp gathering and tra-nsferring plates are withdrawn from the movfing forms and move outwardly awayfrom the same. y

The invention. has for a further object, the provision of a pulp gathering, transferring, squeezing and forming device of this character in which the pulp gathering and transferring plates will be, provided with pulp gathering and transferring screensV upon Vtheir concaved or werking faces and will be mounted in such manner that as the plates move outwardly away from the moving forms, the pulp gathered by the pulp gathering and transferring screens will be forced from the same toward the forms, thereby eliminating danger of the pulp adhering to the screens of the plates and being drawn away from the forms by said screens.

The invention has for a still further object to provide impro-ved and novel' means for guiding the pulp gathering and transferring plates during the inward and outward movement ofthe same and at the same time gathering fluid from the tank during the inward movement of the pulp gathering and transferring plates and forcing said Huid through said plates toward the moving forms during outward movement of said plates to force the pulp away from the working or concaved faces of said plates and toward the moving forms to prevent the pulp transferred to and compressed around said forms by said plates from being drawn away from the forms by the plates as the latter move outwardly and away from said forms.

A still further object of the invention is to provide a pulp gathering, transferring, squeezing, and forming device of the above stated character which may be readily substituted for the primary pulp compressing and squeezing mechanism and also the secondary compressing and squeezing mechanism of the machine as disclosed in our original and Cqpendingapplication, Serial Number 741 or of similar machines are employed in place of the device disclosed in our co-pending application Serial Number 2,051 or the device disclosed in our co-pending application- 'Serial Number 4,035, if desired, the present device being an improvement over the second ment-ioned and the" third mentioned applications as well as the referred to portions of the machine dis-V said secondary compressing and shaping` mechanism of the machine.

l/Vith these and other objects in view, our invention consists inthe novel construction, combination and arrangement of parts as will be hereinafter more in detail described and the asserted novelty specifically pointed out in the claims. Y i l i Figure 1 is a vertical transverse section of the complete device in operation, parts of fthe device being in elevation vand the section beingl substantiallyon thevplane of line 1-1 of Fig. 2, looking in the direction indicated by the arrows; Y

Fig. 2 is a top plan view with the stationary central shaft and the drive shaft in section; j

Fig. 3 is an enlarged fragmentary detail vertical section, on the plane of line SW3 of Fig. 4; and

Fig. l is an enlarged fragmentary transverse horizontal section on the plane' of line fle-4 of Fig. 3, looking in the directionindi-V cated by the arrow.

Referring more particularly to the drawings in which similar reference characters designate corresponding parts throughout the several views,1 designates the pulp containing tank which receives a continuos supply of pulp' from a feed pipe 3 having its discharge end directed toward the'open upper end of said tank 1, as in our co-pending applications Serial Numbers 74:1; 2051; and

In the present device7 as in our original and co-pending applicationl Serial No. 741 `and our third antico-pending application lSerial No. 4035, for similar devices, we em- -ploy a stationary central shaft4, extended vertically through a central opening 5 in the bottom of the tank l and having a kspirally extended feed and guide thread 8 formed' thereon, preferably below said tank 1, to serve to feed and guidein an upward and spiral direction the forms or formervsections A, through the upwardly flared pulp receiving and directing receptacle 6 and through the tank 1, and around said stationary central shaft et.

The receptacle 6 is `preferably of the form shown in our previously mentioned co- `pending applications and is extended upwardly from the edge of the opening 5 in the bottom of the tank 1 and is spaced from the stationary shaft 4; and it will be understo-od that this receptacle 6 may be of any suitable size `and. secured to `thebottom of the tank i in any prretraiteeenkaown manner.` It will also be understood that 'the' forms or former sections A 'should in- V.remainder ofthe forms or former-sections A may be of theconstruction shown and described in our original and (zo-pending ap@ plication Serial Numberial or of any other suitable construction, and therefore further detail description of the forms or formersections A, in this application,'is believed lto be uniiece'ssary. `It is also believed to be unnecessary to show or describe in this application, any nieansfor rotatingthe 'forms or former-sections A, as they may be oper:- ated bythe sectional former rotating mechanism disclosed in said cri-pending application Serial Number 741 or by any other 'suitable means operatively connected with the drive pinion vm'ounted upon the drive shaft Gil, below the tank 1. This drive shaft Gil extends verticallythrough said tank-1 and corresponds to the vertical drive shaft disclosed in said eo-pending application Serial Number 741. l f Y 'I In the present invention we employ pulp gathering and transferring arcuate or transversely curved plates 21, formed preferably of perforated metal and having pulp gathering and transferring screens 22 mounted upon their working orconcave inner faces, f

for gathering plup from the pulp containl ing tank l and transferring said pulp to the moving forms or former-sections A and partially compressing the saine upon said forms or former-sections A, as the latter g pass upwardly in a spiral'direction through said tank 1 and the plates 21 move inwardly and outwardly and travel around 'said forms or former-sections A, as will be later clearly understood.

The pulp gathering and transferring plates 21 are of substantially rectangular form in general outline and are arranged in a circular series within the pulpA contain ing tank 1 and around the stationary central 'shaft 4 and -the moving` forms or formersections A traveling upon the latter.

The upper or extended ends of the pulp gathering and transferring plates 21 project above the pulp level line B and said plates v21 are preferably in different horizontal planes so that the upper and lower edges of the various plates 21 are offset from one another to prevent the creation of joints or seams in the pulp transferredto and comi pressed varoundsaid forms or former-sec tions A by said plates 21.

The pulp gathering and transferring plates2l form theend or head platesofthe reciprocating cylinder heads 23. Each reciprocating cylinder head 23 has a continous flange 24 formed around its open inner end, around which flange 24 is secured one end of abellows 25, the opposite end of which is secured around a stationary inner cylinder head 26, mounted in, a suitable manner upon a casting 27 which in turn is mounted upon a supporting shaft 28.

Each casting 27 is secured to an external gear ring 29 by means of screws 30 or other suitable securing members passed through an upwardly directed flange 31 formed on an extension 32 of said casting, said securing members 30 also being extended into the eX- ternal ring gear 29, against the inner smooth face of which said flange 31 is engaged. The external ring gear 29 rides upon the lower arms 33 of the supporting brackets 34 secured to the inner face ofthe pulp containing tank 1 and displacement of the external gear ring 29 is prevented by the upstanding centering lugs 35 formed on said lower arms 33.` The external ring gear 29 is rotated upon the supporting arms 33 by means of a drive pinion 36 keyed upon the drive shaft 64 and meshing with the teeth of saidl eX- ternalring gear 29 to carry the supporting shafts 28 and parts mounted thereon around the moving forms or former-sections A and in the direction of rotation of the forms or former-sections A.

rl`he castings 27 are connected and braced by the ring 37 engaged i-n the bearing ears 38 which project outwardly from the upper portions of the castings 27, as will be readily understood by referring to the drawings, and as the external ring gear 29 is rotated to carry the supporting shafts 28 and the castings 27 and parts mounted upon the same around the moving forms or former sections A, said supporting shafts 28 are caused to rotate within the castings 27, by means of the driven pinions 39- keyed upon said supporting shafts 28 and meshing with the teeth of the stationary'internal gear ring 40. Suitable securing members 41 are employed to secure the stationary internal gear ring 40 to the ends 42 of the upper arms 43 of the castings 34, previously mentioned.

The opposite ends of the supporting shafts 28 areextended beyond the castings 27 and have mounted thereon, the rigid cam disks 44, from which project the eccentric pins 45. Loosely mounted upon each eccentric pin 45 is a collar 46, which is prevented from working off of the same, by means of a suitable pin 47 passed transversely through said ec-,

centric pin 45. Each collar 4G is provided with a pair of ears 48, betweenwhich is pivoted one end of a pitman arm 49, by means of a pivot pin 50 passed through the same and through said ears 48.

The 'opposite end of each pitman arm' 49 is pivoted; between a pair of ears 51 of a eol-v lar 52, by means of a suitable pivot pin 53. The collars 5,2, however, are loosely mounted upon the upwardly and downwardly eX- tended pintles 54 projecting from the top and bottom faces of the reciprocating cylinder head 23 opposite and connected with the casting 27 above and below which said pitman arms 49 are positioned. The collars 52 are prevented from working olf of the pintles 54 by suitable pins 55 passed transversely through the ends of said pintles 54.

It will be readily seen that upon rotation of the supporting shafts 28, the pitman arms 49 will be operated to reciprocate the reciprocating cylinder heads 23 and move the pulp gathering and transferring plates 21 with their screens 22 toward and away from the moving forms or former-sections A. rlhe reciprocating cylinder heads 23 are guided in their movements with respect to the forms or former-sections A and the castings with which said reciprocating cylinder heads 23 are connected, by means of upper and lower guide arms 56 sliding in the guideways 57 formed on extended upper and lower portions of the castings 27. vThe guide arms 56 project radially from the collars 58 which are non-rotatably mounted upon the pintles 54, inwardly of the collars 52, thereby preventing the reciprocating cylinder heads 23 from turning to one side during operation of the device.

While any suitable number of castings 27 and reciprocating cylinder heads 23 with the screen covered pulp gathering and transferring plates 21 may be employed, we prefer to use an even number of the same, as shown in the drawings, with the reciprocating cylinder heads 23 connected with the cam disks 44 by means of the pitman arms 49 in such manner that while alternate reciprocating cylinder heads 23 are in their innermost positions with the screens 22 of the pulp gathering and transferring plates 21 engaged against the pulp around the movingV forms or former-sections A, the remaining reciprocating cylinder heads 23 are in their outermost positions, as will be readily understood by referring to Fig. 2 of the drawings. It will therefore be evident that as one set of pulp gathering and transferring plates 21 moves outwardly away from the moving forms or former-sections A to gather a fresh supply of pulp to be transferred to said moving forms or former-sections A, the remaining set or alternate pulp gathering and transferring plates 21 move inwardly to deposit a fresh supply of pulp upon the outer screens or faces of said moving forms or former-sections A.

As each pulp gathering and transferring plate 21 travels around the moving forms or former-sections A and at the same time moves inwardly toward said forms or former-sections A, it gathers pulp from the tank 1, upon the outer face of the screen 22 upon the concave or working face of said .pulp gathering and transferring plate 21, and then transfers this pulp to the outer face of said moving forms or former sections A, liquid from the pulp passing through the screen 22 and through the perforations of the pulp gathering and transferring plate 21, into the bellows 25. After the pulp has been transferred to the outer face of the'moving forms or former-sections A from the screen 22 and partially or completely compressed upon said forms or former-sections A b y said screen 22, the latter together with the pulp gathering and vtransferring plate 21 and the complete reciprocating cylinder head 23, moves outwardly as it continues its movement around said moving forms or former-secti ons A and during this outward movement of these parts of the device, theV bellows, 25 serves to force outwardly the liquid gathered therein, through the perforations of the pulp gathering and transferring plate 21 and its screen 22 and toward the moving forms or formersections A, thereby forcing the pulp away from the screen 22 and against the moving forms or' former-sections A and preventing this pulp from being again drawn away from said forms or former-sections A Vby the receding pulp gathering and transferring screen 22 and plate 21.

By referring to Fig. 3 of'the drawings, it vwill be seen that the upper guide arm 56 normally rests in the bottom of the upper guideway 57 while the lower guide arm 56 is suspended in the lower portion of the lower guideway 57. This will permit an upward movement of the reciprocating cylinder heads 28 and the pulp gathering and transferring plates 21 and screens 22 carried by the same when said screens 22 are engaged against the pulp deposited and compressed upon the moving forms or former-sections A, thereby making it possiblev for said screens 22 to move in a spiral direction 'with said forms or former-sections A while depositing and compressing pulp upon the same. Y

From the foregoing description taken in connection with the accompanying drawings, it is believed that the construction and operation of the complete device will be readily understood and that it will be apparent that the present device will produce a continuous output free' of seams, and it is thought that a further detailed description of the device is unnecessary.

While thepreferred embodiment of our invention has been Shown and described, it will be understood that the form of the pulp gathering and transferring members may be varied at will and caused to perform the complete compressing operation or only a part of the same as desired and many minor changes in the details of construction and arrangement of parts may be resorted to within the scope of the appended claims.
